Virtualization technology originated on mainframe computers in the 1960s to more efficiently utilize processing power. Early virtualization methods were difficult to manage for dynamic business needs. This led to innovations in virtualization strategies and technologies over time. Key developments included the first hypervisor in 1965, IBM's CP-40 implementation in the 1970s, and increased popularity on personal computers in the 1980s-1990s. VMware introduced desktop and server virtualization products in the late 1990s and 2000s that helped drive broader adoption.
